Dihydrotanshinone

	Dihydrotanshinone Dihydrotanshinone I (DI) is a naturally occurring compound extracted from ''Salvia miltiorrhiza'' Bunge, also known as Chinese sage, red sage root, and the Chinese herbal Dan Shen. It belongs to a class of lipophilic abietane diterpenoids and has been reported to have cytotoxicity to a variety of tumor cells, as well as antiviral Antiviral drugs are a class of medication used for treating viral infections. Most antivirals target specific viruses, while a broad-spectrum antiviral is effective against a wide range of viruses. Unlike most antibiotics, antiviral drugs do no ... effects ''in vitro''. Since they were first discovered, over 40 related compounds and over 50 hydrophilic compounds have been isolated from Dan Shen. References Diketones {{organic-compound-stub ...

	Salvia Miltiorrhiza ''Salvia miltiorrhiza'' (), also known as red sage, Chinese sage, tan shen, or danshen, is a perennial plant in the genus ''Salvia'', highly valued for its roots in traditional Chinese medicine. Native to China and Japan, it grows at elevation, preferring grassy places in forests, hillsides, and along stream banks. The specific epithet ''miltiorrhiza'' means "red ochre root". Chemical constituents Chemical compounds isolated from ''Salvia miltiorrhiza'' include salvianolic acid (or salvianolic acid B), dihydrotanshinone, miltirone, tanshinone I, and tanshinone IIA. Tanshinone IIA is one of the most abundant constituents of the root of ''Salvia miltiorrhiza''. Description ''S. miltiorrhiza'' is a deciduous perennial with branching stems that are tall, with widely spaced leaves that are both simple and divided. The inflorescences are covered with hairs and sticky glands. Flowers grow in whorls, with light purple to lavender blue corollas that are approximately long, with a ...

	Lipophilicity Lipophilicity (from Greek λίπος "fat" and φίλος "friendly"), refers to the ability of a chemical compound to dissolve in fats, oils, lipids, and non-polar solvents such as hexane or toluene. Such non-polar solvents are themselves lipophilic (translated as "fat-loving" or "fat-liking"), and the axiom that "like dissolves like" generally holds true. Thus lipophilic substances tend to dissolve in other lipophilic substances, but hydrophilic ("water-loving") substances tend to dissolve in water and other hydrophilic substances. Lipophilicity, hydrophobicity, and non-polarity may describe the same tendency towards participation in the London dispersion force, as the terms are often used interchangeably. However, the terms "lipophilic" and "hydrophobic" are not synonymous, as can be seen with silicones and fluorocarbons, which are hydrophobic but not lipophilic. __TOC__ Surfactants Hydrocarbon-based surfactants are compounds that are amphiphilic (or amphipathic), having a hy ...

picture info	Abietane Abietane is a diterpene that forms the structural basis for a variety of natural chemical compounds such as abietic acid, carnosic acid, and ferruginol which are collectively known as abietanes or abietane diterpenes. Abietanes are found in the tissues and resins of certain higher plants, particularly gymnosperms. Although the functions of terpenes are not fully understood, conifers appear to produce abietane diterpenoids as a form of defense against insect and microbial attack. Some abietane diterpenoids, especially aromatic abietenes, are of interest to the pharmacology and natural products communities for their potential biological activities. In the rock record, abietanes are commonly found in amber as well as in fossil wood, sometimes in the form of the mineral fichtelite. Additionally, abietanes are observed in sediments—both riverine and marine—and in coals, where they are often interpreted as geochemical biomarkers for terrestrial input from conifers.

	Terpenoids The terpenoids, also known as isoprenoids, are a class of naturally occurring organic chemicals derived from the 5-carbon compound isoprene and its derivatives called terpenes, diterpenes, etc. While sometimes used interchangeably with "terpenes", terpenoids contain additional functional groups, usually containing oxygen. When combined with the hydrocarbon terpenes, terpenoids comprise about 80,000 compounds. They are the largest class of plant secondary metabolites, representing about 60% of known natural products. Many terpenoids have substantial pharmacological bioactivity and are therefore of interest to medicinal chemists. Plant terpenoids are used for their aromatic qualities and play a role in traditional herbal remedies. Terpenoids contribute to the scent of eucalyptus, the flavors of cinnamon, cloves, and ginger, the yellow color in sunflowers, and the red color in tomatoes. Well-known terpenoids include citral, menthol, camphor, salvinorin A in the plant '' Salvia divino ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Antiviral Antiviral drugs are a class of medication used for treating viral infections. Most antivirals target specific viruses, while a broad-spectrum antiviral is effective against a wide range of viruses. Unlike most antibiotics, antiviral drugs do not destroy their target pathogen; instead they inhibit its development. Antiviral drugs are one class of antimicrobials, a larger group which also includes antibiotic (also termed antibacterial), antifungal and antiparasitic drugs, or antiviral drugs based on monoclonal antibodies. Most antivirals are considered relatively harmless to the host, and therefore can be used to treat infections. They should be distinguished from viricides, which are not medication but deactivate or destroy virus particles, either inside or outside the body. Natural viricides are produced by some plants such as eucalyptus and Australian tea trees. Medical uses Most of the antiviral drugs now available are designed to help deal with HIV, herpes viruses, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
